WRAPPING MACHINE.

Application iiled August 4, 1922. Serial No. 579,737.

To all whom t may concern.:

Be it known that I, JoiiN SCHERNER, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of lVisco-nsin, have invented new and useful vImprovements in Wrapping Machines, of which the following is a description, reference being had to the accompanying drawings, which are a part of this speciication.

This invention relates to wrapping machines,fand more particularly to machines for wrapping rubber tires, such as motor vehicle tires or casings, with a spiral wr'apping or covering strip of paper or other suitable material. f

The essential object of the invention is to provide a wrapping machine iii which the spirally' wound covering strip is supplied with adhesive to unite the adjacent edges of the turns of the stripas'it isv wound about the tire so that the covering will be firmly held in place and will be prevented from unwinding, even if broken in spots, the censtruction providing a simple and positive feed of the adhesive to the wrapping` material. i

The invention further consists in the several features hereinafter seti forth and more particularly defined by claims at the conclusion hereof. t U In the drawings: Fig. 1 is a side elevation of a wrapping machine embodying the invention; Fig. 2 is a detail sectional v iew taken on the line 2 2 of Fig. 1; Fig. 3 is a detail plan view of parts of the machine;

Fig 4 is a detail plan view of parts of the machine; Fig. 5 is a detail elevation of parts of the machine.

In' the drawings the numeral 6 designates a supporting table carrying a, bracket. Vt upon which rollers 8 are mounted which receive a belt 9 that runs over a drive pulley 10, the drive pulley, as shown, being driven bv a'frictionwheel 11 on the shaft of an electric motor 12. An annular shuttle 13 is mounted between the rollers 8 and pulley 10 and is continuously rotated by running a portion of the belt 9 about the shuttle and then over the pulleys 8, as shown in the drawing and as well understood .by those skilled iniths art. The articlejto be wrapped, such as a tire casing 14, is supported upon spaced rollers 15, only one being shown, and a guide roller 16, in a well known manner, so that the tire moves through the eye or central openingr of the shuttle as the shuttle revolves. As shown, the roller 15 is driven through a chain drive 17 from a shaft 18 having a gear con-v nection 18 with the shaft 19 of the pulley 10, all of which is of well known construction.

A reel of paper or other suitable wrapping material 2() is mounted at a Ysuitable point upon the shuttle 13 and passes over an arcuate guide table 21 carried by the shuttle and from there to a guide roler 22 and then over the tire. The length of this arcuate table is preferably equal to abbut half the i;

before the same passes down to the roller 22.

The means for applying the adhesive t0 the wrapper strip consists of a tank 25 containing adhesive into which a ro-ller 26,

mounted on a shaft 27, is partially im- ImerSed. The shaft 27 is joui'nalled in the 'forked arms 2S of a bracket 29 which is pivotally mounted intermediate its ends 'at' I 29 upon the tank. The-roller 26 is yield ingly held against a part of the wrapper strip by a spring connected to the outer l end of the aini 31 of the bracket and to the tank. lThe roller is prevented from interferiiig` with the proper operation of the shuttle and the feed of material to the table by means ofa stop, such as an adjustable set screw 32 on the arm 31 engageable with a fixed part 33 of the machine. The roller 26 is pivotallydriven from the shaft 18 or other positively driven part of the machine in any suitable manner, as by means of a belt 34; running over a pulley 35 on the shaft 27, a pulley 36 on the shaft 18 and guide pulleys 37 and 38. The shuttle 13 and the i'olleil 26 turn in opposite directions, as

indicated by the arrows iii Fig. 1. `In order to prevent spasli and to regulate the amount of adhesive supplied to the wrapper strip,

a member 39 is pivotally mounted on a shaft 40 to which it may be locked in adjusted position by a thumb screw 41 and said member is notched adjacent the roller so that a part 42 and parts 42 are closely spaced ,-frcm the periphery and :sides of the roller so` that only a thin film of adhesive i's' .carried up by the roller and deposited on the strip. By loosening the screw41the memberv 39 may swing upwardly. While the Whole strip may have adhesive applied thereto, it is only necessary to apply adhesive Where the spira-l turns overlap eachother 'and consequently theroller 26 is narrower than the strip of Wrapping material applied to the tire.

With the above construction, as `the tire or casing moves through the rotating shuttle 'the Wrapping strip o n the reel QOyis unwound .therefrom and Wound up as a spiral covering upon the tire, and as this covering strip S runs along 4the table 21 1t -receives adhesive from the roller 2G so that adjacent'convolutions ,of the Wrapping are suitably united together, the long table insuring a proper supply of adhesive tot-heentire length of paper asv it comes from the roll. This construction insures a simple,

direct feed of adhesive to the covering material prior to its being wound up around the tire Without danger of stoppage of rotation of the feed roll. As is Well understood,

lthe shuttle has a hinged section which permits the placing of the tire in positionfor Winding purposes.

I desireit to be understood that this invention is'not to be limited to any specific form or arrangement of parts except in s o far as such limitationsv are specified in the claims.

' What I claim as my invention is:

1. In a Wrapping machine, the combination with mechanism for wrapping a covering stri spirally about a tire or tire casing, the mec anism including a rotating shuttle i carrying the wrapping material, of an adhe- `tle for, positively driving said member, and

siveapplying member mounted adjacent 'said shuttle, means distinct from said shutmeans for ffuiding the material int-o feeding contact with said member.

In a wrapping machine, the combination with mechanism for wrapping a covering strip spirally about a'tire or tire casing,

the mechanismincluding a rotating shuttle I l. carrying the wrapping material, of a table on the shuttle upon which the material moves, a positively driven adhesive-applying roller, means for yieldingly pressing sald roller into contact with said material While passing on said table, and means for limiting the movement of said roller toward the shuttle.

3. In a wrapping machine, the 'combinal-i :for limiting the movement of said roller toward the-shuttle. 4l. In a Wrapping machine, the combination with mechanism for Wrapping a covering strip spirally about a tire or tire casin 'the mechanism including a rotating shuttI carrying the wrapping material, of a table on the shuttle upon which the material move's,"a tank, a tilting support, av positively driven roller mounted on said -support and dipping into the adhesive in said tank, means for limiting the tilting movement'of said support, and means coacting with said support to yieldingly press the roller into contact with said material While passing over said table.v

5. In a wrapping machine, the combination with mechanism for Wrappingr a covering strip spirally about a tire or .tire casing` fthe mechanism including a'rotating shuttle carrying thewrappingA material, of a table on the shuttle upon which the material moves, a tank, a tiltinosupport,'a positively .driven roller mounted dipping into the adhesive in'said tank, an adjustable stopon saidsupport to limit the tilting movement thereof, a member in close proximity to theface and sides of the roller` at its advancing side to prevent splash and regulate the feed of adhesive to the material, and means coacting With said supon Said support and' port to yieldingly press the roller into contact with said material while passing over said table. Y

6. In a wrapping machine', the combina'- tion with mechanism or Wrapping a cover ing strip spirally about a tire or tire casin the mechanism including a rotating shuttlie carrying the wrapping material, of a springpressed positively driven adhesive-applying roller mounted adjacent said shuttle, an

In testimony lwhereof, I nia my signature.
